StressCheck Tutorial: 3D Modeling of a Skin-Stiffener-Fasteners Assembly (In-Plane Contact)
Abstract: Modeling of a 3D skin, stiffener and fasteners (as cylindrical shanks, no heads/nuts) assembly for an in-plane multi-body contact analysis. In-plane axial loads only, in which the stiffener/skin load ratio is 0.55. Defining parts for each subassembly for easier creation and assignment of contact zones. Model pre-processing only.

“In the case of the through crack configuration, the comparison of experimental and StressCheck® derived geometry factors showed a close correlation and were an improvement to solutions provided in AFGROW at the time. Based on the results of this research, StressCheck® pin-loaded lug geometry factors have since been incorporated into the AFGROW software.”
